Yum dependency available but not marked for install

Question

I'm trying to install a specific version of MySQL: mysql-community-server-5.6.29-2.el6 on RedHat 6.6.

When I run yum install, I get dependency errors, but the dependencies are clearly available. I'm not sure how to proceed.

It looks like something is requesting MySQL-community-libs-5.7.11-1.el6, but I don't know how to force it not to.

Useful output:

[root@cl-mgr01 ~]# yum install mysql-community-server-5.6.29-2.el6

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Other useful output:

[root@cl-mgr01 ~]# rpm -qa | grep mysql
mysql-connector-java-5.1.17-6.el6.noarch
mysql-libs-5.1.73-3.el6_5.x86_64

Try following:

# yum install --enablerepo=mysql56-community install mysql-community-server

Package mysql-community-server-5.6.30-2.el7.x86_64 already installed and latest version
Nothing to do
# 

... better yet, using yum-config-manager, disable mysql57-community and enable mysql56-community, then install mysql-community-server.

# yum repolist | grep mysql

Answer 2

What I had to do in the end is the following:

• Upgrade MySQL-libs using yum update mysql-libs, which installed mysql-community-libs
• Downgrade them using yum downgrade mysql-libs so that they were on 5.6.29
• Install mysql-community-server
